The engineer of the train, 32-year-old Brandon Bostian of Queens, N.Y., and the conductor, who still has not been identified, survived the crash. Bostian's attorney told ABC News that the engineer "suffered a concussion" and has "no explanation" as to why the train derailed. Directly after the crash, Bostian did not provide an official statement to police when they inquired.
According to Bostian's LinkedIn page, he began working at Amtrak as a passenger conductor in 2006. Four years later, he became a passenger engineer.
The train's speed may have played a part in the crash, CNN reports:
"Initial data show the train barreled into a curve at about 106 mph, National Transportation Safety Board member Robert Sumwalt said. That's more than twice the 50-mph speed limit for the curve, and above the 80-mph limit immediately before it."
